SPECIFICATION forming part of Letters Patent No. 269,208, dated December 19, 1882.

To all whom Ait may concern.-

Beit known 'that l, DANIEL M. HOOK, of Columbia, in the county of Richland and State of South Carolina, have invented certain Improvements in Water-Wheels, ot' which the following is a specification.

My invention relates to water-wheels; and it consists in Aarranging two turbine wheels one below the other, with a stationary water-way between them, the wheels being carried by independent shafts one encircling the other.

The invention further consists in other features and details hereinafter fully explained.

ln the accompanying drawings, Figurel represents a vertical central section of my improved double wheel and casing; Fig. 2, a side elevation ot' the same with the casing in section 5 Fig. 3, a top plan view of the easing with the top removed to show the arrangement of the water-inlets and the gate.

The object of my invention is to more fully utilize the power ofthe water 5 and to this end it consists in placing one wheel below another mounted, said casing being formed with a water-inlet at the top, and a water chamber or channel, a, preferablynairowing as it extends around the gate B, which consists of an annular rim or cylinder arranged to move vertically within a series ot' tangential guides ordirecting-plates, b, between which the water passes to the upper wheel, O, the guides or plates causing the water to strike the blades or buckets of the wheel near the top and well out to ward their outer edges, where they aord the greatest leverage. The impact or percussion being thus utilized, the weight and the reaction ot' the water are utilized as the water glides down the inclined buckets in the ordinary and well-known manner.

The wheel C is carried by a tubular shaft, D, stepped at c, and a second wheel, E, is placed some distance below the first and carried by a shaft, F, which passes centrallyr through shaft D, and is stepped in a block, d, as shown in Fig. l. The wheel E is driven by the waste or discharge watenfrom wheel C; but as the water islikely to fall straight downward from the lirst wheel, especially if said wheel is so formed as to utilize to the best advantage the force ot' the water, I provide a stationary waterway, G, between the two wheels, inclining the water-passages at such an angle as tov canse the water to strike the buckets of the second wheel near the top, and substantially at right angles to their face, the wheel being constructed in all respects like the wheel C, except that it is larger in diameter. This increase in diameteris made to at'- i'ord a free discharge t'or the water, which, having in a measure lost its force or been checked in acting upon wheel C, might otherwise back up and interfere with the tree action of the first or upper wheel.

rThe shafts ofthe two wheels may be geared together by differential or compensating gear; or they may be independently connected with different machinery, as found desirable.

am aware that it is not new to place one wheel below another, so that the lower one shall be driven by the water escaping or discharged from the upper and' smaller wheel, said wheels being mounted upon independent shafts; but such wheels have always, so far as I am aware, been arranged to run in reverse directions, and have not been furnished with an intermediate water-way.

I am also aware that two or more wheels have been secured to the same shaft at intervals with intermediate water-ways; but since the rst wheel turns or naturally would turn faster than the others, because ot' having the tirst and full force ofthe water, it follows that the other wheel or wheels will turn in dead water, and thus retard instead of assisting the rst wheel.

The gate B consists simply ot' a ring or holthe wheel C and the guides or plates b, being raised and lowered by rack and pinion or other suitable gear. Being within the guides, it cuts 0E the water close to the wheel and stops the wheel quickly and with little or no Waste. The guides or plates also serve to support and guide the cylinder in its vertical movement, and to sustain it against lateral pressure at any point.

Y low cylinder, arranged to rise and fall between within the guides or plates b, and between ment Iam enabled to utilize to the fullest ex- It will be observed that the wheel-C extends somewhat above the bottom of the surrounding Water chamber or inlet a, so that the water entering between the directing-plates or guides is caused to strike the outer edges of the blades or buckets and to act in the direction of rotation of said. wheel, after which it falls, and,aeting upon the baoliwardly-inclined buckets, gives still further power or effect in turningr said wheel, thus utilizing the power both of direct action and reaction in the highest possible degree. The gate or cut-off, being them and the wheel C, eli'ectually outs oft' the delivery to the wheel and prevents the waste of any water whatever.

By my improved construction and arrangetent the power of the Water both by direct action and by reaction.

Having thus described my invention, what I claim isl. The combination of two turbine waterf wheels,mounted uponindependent shafts, one l above the other, and an intermediate waterway to give direction to the water escaping from the rst wheel and to insure its proper delivery to the second Wheel, substantially as explained.

2. The combination of two water-wheels, one

placed beneath the other, and mounted upon independent shafts, the upper wheel being smaller than the lower, and an intermediate stationary water-way, arranged to deliver the water at the proper angle from the upper to the lower wheel, substantially as shown and described.

3. In combination with the-casing A, having guides or directing-plates b, a verticallymoving annular gate, B, arranged within said guides, substantially as shown, whereby they are caused to guide and sustain the gate, as explained.
